SPECIFICATION forming part of Letters Patent No. 264,897, dated September 26, 1882.

Application led January 3, 188'2.

To all whom it may concern Be it known that I, SrvERr PnDERsoN, a subject of the King of Sweden and Norway, and a resident of Menomonee, in the county of Dunn and State of Wisconsin, have invented certain new and useful Improvements in Gylinder-Guns, of which the following is a specification.

This invention relates to that class of ordnance or re-arms in which the loading and firing are both accomplished by mechanical means; and it consists in a cylinder provided with ammunition-chambers in its'periphery, and adapted to be revolved, and with means for loading and capping said ammunition-chainbers while the cylinder` is being revolved, and firing the charges through a series of barrels corresponding to any desired number of the said ammunition-chambers, as hereinafter set forth. I attain these objects by theuse of the mechanism illustrated by the accompanying drawings, in which- Figure l is a sectional side elevation. Fig. 2 is an outside View of the rear portion. Fig. 3 is a sectional view of the casin g and a portion of the barrels with the cylinder removed, illustrating the construction of the capping and tiring mechanism. Fig. 4 is a detached view of the ham mer-operatin g mechanism; Fig. 5, an enlarged detached view of the cam-shaft and its attachments for operating the capping and firing mechanism; Fig. 6, an enlarged sectional detail view of a portion of the cylinder and capping mechanism. Fig. 7 is a sectional plan view. Fig. 8 is a semi-sectional front view of the cylinder, barrels, casin g, and ammunition-magazine. Fig. 9 is an enlarged crosssection of the cylinder and a portion of the magazine and barrels, and Fig. 10 is a longitudinal section of the same. larged perspective view ot a portion of one end of one of the sections of the cylinder detached.

A is the axle, B B2 the' wheels, and C the carriage formed in the ordinary manner of a cannon-carriage.

Mounted by trunnions a a2 upon the carria ge C, and adapted to be elevated or depressed in the ordinary manner by a screw, b, to secure the proper range, is aframe or casing, D, having secured thereto a metal block, E, pro- Fig. 11 is an en# (No model.)

true and in aperfect circle about the center of 6o the cylinder. The rear of the barrel-block E is formed hollow to t the sections G closely, as shown. Each of the sections G is provided with a number of chambers, d, corresponding in number and position to the barrels c, so that when one of the sections is opposite th'e barrel-block the chambers d of said section will be directly in line with and opposite to said barrels. Upon the lower part of each of the sections G is a rib, e', (see Fig. 11,) having a groove, c2, running its entire length, and with small holes or vents crunning from the grooves into each of the chambers d. The ribs c are adapted to fit into corresponding cavities in the surface of the cylinder F, and opposite each of said cavities and leading into the channels c2 are nipples g, upon which percussioncaps are to be placed, as hereinafter shown.v

By this means, if the chambers d in one section be charged with powder and ball, and a percussion-cap tired on the nipple g corresponding thereto, the re will run through the groove cZ and up through the vents c3 and ignite the powder in all the chambers of each section with one cap.

Above the cylinder is a magazine or'ammunition-boX, H', divided into two compartments, H2 H3, each compartment being provided with a bottom, 71,' h2, between which and the bottom proper of the magazine slides 7b4 h5 are arranged to be pulled out and pushed in through the ends ofthe casing H. Each ot' the bottoms 7L h2 and the slides 71.4 h5 are provided with perforations h6 hl, corresponding in number to the chambers d of one ofthe sections G, while similar perforations or conduits, 708, connect the perforations 7W of the slides 7LJi h5 with the chambers d of the sections G. The conduits 7L8 are arranged so that when the sections G come beneath them each chamber d of two sections will have a conduit above it at the same time that the forward section is opposite the barrels c, as shown in Fig. 9. The perforations h6, through the bottoms h' h2, are not directly above their corresponding conduits, ha, but to one side, as shown in Fig. 8, so that when the slides are moved outward to bring the perforations h" beneath the perforations'h6 the solid portions of the slides will come above the conduits ha, and then when moved back again the perforations hFI will come above the conduits h and bring the solid portions of the slides beneath the perforations h6. .The powder will be placed in the compartment H2 and the balls in the compartment H3. The slide h4it will be observed, is much thicker than the slide h5, to provide a space within its perforations k7 sufficiently large to hold a charge of powder for the chambers d, while the slide 71.5 need only be thick enough to hold one bullet in each of its perforations. The perforations for the powder, it will also be seen, are much smaller than the perforations for the bullets, as less space laterally is required for the former than for the latter. A strip of rubber or leather, fi, will be arranged in the lower face of the magazine H' between the compartments H2 H3, to act as a wiper77 to the sections and prevent loose powder being carried over to the barrels. The low' with the same number of teeth that there are sections G, (in the drawings 9,) and surrounded by a ring, K2, having` a dogv adapted to engage with the teeth of the ratchet.

m is a lilik or rod connecting the collar K2 with thelower end ofa liand-lever, M', mounted upon a shaft, M2, journaled across the rear of the cylinder F on the frame D. By this arrangement, if the hand-lever M be pushed forward at the top, the collar K2 will be revolved backward around the ratchet K', and then when pulled back again the dog, acting upon the ratchet-teeth, will revolve the cylinder.

In the edges ot' the sections G small cavities n' are formed, in which the point of a springpawl, n2,ts. (See Fig. l.) This spring-pawl is provided upon its upper side withv a springcatch or stop, n3, upon which the toe77 of a dog, n4, catches. This dog is connected by a rod, a5, to an arm, iis, on the shaft M2, so that when the shaft is revolved backward the dog n4 will be raised up, and by means of the toe of the dog catching upon the catch n3 of the springpawl n2 will draw the spring-pawl backward and removeits point outward from the cavity n', in which it tits. v By this means, when the pawl n2 is engaged with one of the cavities n. the cylinder F and its attached sections-G will be held stationary; but when the latter is to be revolved the saine backward movement ot' the hand-lever Ml that operates the ratchet K will also release the spring-pawl n2 and permit the cylinder to be revolved. The lifting of the dog n4 will in time release its hold on the catch n3, when the spriiig-pawl n2 will be thrown forward again by its spring, ready to engage with the next cavity, a', and then when the lever Ml is pushed forward again the dog n4 will again engage with the catch n3. v Upon the opposite end of the shaft M2 is a segment of a bevelgear, M3, adapted to mesh into a similar segment, M4, upon a shaftjournaled at right angles to the shaft M2 in the side of the casing v D. This cross-shaft is formed of two parts,

one part, M5, being a hollow sleeve, (see Fig. 5,) and having the segment M4 rigidly attached thereto, as shown, and the other part of the shaft M6 passing through the sleeve M5. One end of the part M is journaled at M"l in the casing D and the other end journaled at M8 in the box of the shaft M2, while a cap, M9, supports it at the center, the hollow sleeve M5 ruiming upon the part M6 loosely.

Upon the end of the shaft M6, between the segments M4 and bearing M8, is a clutch-collar, N, having teeth t t2 upon the side next the segment M4, adapted to tinto corresponding cavities in said segment when the clutchcollar is moved along the shaft toward the segment, and a tooth, t3, upon the opposite side adapted to t'into a corresponding cavity in the box of the sha-ft M2 when the clutch-collar is moved over against it, the distance between the segment M? and bearing M8 being snfcient to allow of the proper movement of the clutchcollar N to hold the teethz tZ t3 entirely disconnected from either the segment or bearing,

or connected to either one of them. Ashipperlever, N2, (see Fig. 3,) with a spring, N3, is arranged in tlieordinary manner to throw the clutch-collar Nl back and forth along the shaft Mi to alternately engage and disengage the teeth t t2 t3 with the segment M4 and bearing M8. By this means, it' the clutch-collar N be thrown back by the shipper until the teeth t t2 are disconnected from the segment and the tooth t3 connected to the rigid bearing M8, the segment and sleeve M5 may be oscillated independently of the shaft M6, and the latter held stationary by the clutch-collar N', being fixed tothe bearing M8, and then,ifthe teeth t t2 be thrown in contact with the segment M4 and the tooth t3 detached from the bearing M8, the sleeve M5 and shaft MG will be connected together through the feather and groove of the clutch-collar N and shaft M, so that the oscillation of the segments will also oscillate the shaft M6, as and for the purpose hereinafter explained.

Upon the sleeve M6 are two arms, M1", connected together by a crossrod, M11, the latter adapted tott into a slotted hanger, hg, pro- IOO I'Io

jecting from the end of the slide h4, while similar arms, M12 M13, are arranged to act upon a slotted hanger projecting from the slide h5. By this means it will be seen that the moving of the lever Ml back and forth to revolve the cylinder, as before described,will also, through the segments M3 M4 and sleeve and shaft M5 M6 and arms M1o M11 M13 M13 and hangers hg, move the slides h4 h5 back and forth to` feed the powder and balls to the chambers d.

Below the sleeve M5 is a short plunger, u', (see Fig. 6,) provided with prongs u2 a3, in which the lower end of a lever, c4, pivoted at a5 in any suitable frame upon the casing D, fits, and adapted to be acted upon by an arm, M14, projecting downward from the sleeve M5, to throw the plunger u inward toward the end ofthe cylinder F,while a spring serves to throw it back again when the arm M11 releases it.v By this means the plunger .u will be moved through the casing D, as shown in Fig.' 3, with its lower end opposite the plunger u', while the position of the latter will be such that the nipple g of the section G, beneath the powdercompartment H2, will be directly opposite the plunger and the holes through the tube. By this means the lower cap in the tube P, being opposite the holes in its lower end, will be forced out by the plunger u when the shaft M6 and sleeve M5 are oscillated, as before described, and set over the nipple g opposite to it. Then when the plunger u is drawn back again the weight of the caps above will force the neXtcap down into place, ready to be forced out upon the next nipple g when the cylinder is revolved. A number of the tubes P, ready charged with caps, will be provided, so that no delay may occur in supplying caps to the gun.

Beneath the arms M12, upon the shaft M3, is another arm, M15, projecting downward therefrom, and having a pin at right angles from its lower part adapted to act upon a lever, V', upon a plate, V3, secured to the casing D, to disconnect its lower point or toe from a lever, V3, upon the hammer-pivot when the shaft MG is oscillated.

The hammer V4 is formed in any well-known shape, and has an arm, V3, before described, attached to its pivot, so that the backward movementof the arm M15 may reset the hammer by throwing the teeth V5 into gear with the toes of the lever V. This arrangement is more clearly shown in Fig. fl.

When first operating the gun the shipper N2 is pushed forward to throw the sleeve M5 and shafts M6 out of gear with each other, so that the slide h5 will not be operated to feed balls to the chambers d in advance of the powder. By this arrangement the simple pulling of the lever M' backward revolves the cylinder F and sections G the distance of one of the said sections, draws the slides h4 h5 to fill their perforations with powder and balls, and draws the plunger u back ready to force a cap upon the nipple g, and at the same time sets77 or cocks i the hammer V4. Then at the forward or return stroke of the lever M', and while the cylinder F and sections G are held stationary by the-parvis n3, the plu/nger u is pushed inward and a cap forced upon the nipple g, which may be opposite to it, the slides h4 and h5 pushed back again to permit the powder and balls in them to fall into the chambers d in the sections G beneath them, and the section that is opposite the barrels c red by the trigger or ham- `mer V4 striking the cap opposite to it. The

whole operation of loading, capping, and firing is thus accomplished by the simple movement back and forth of the lever M.

The casing D will be provided with hinges R, so that it may be turned back upon the barrels E when access is required to the barrels, Src.

The barrels c may be made separately and secured in the proper position in the frame, if desired, and the barrels will also be arranged with their nozzles7 farther apart than their ,breeches,77 to cause the balls to sweep over a wider eld when fired than if the barrels were parallel.

l. The cylinder F, adapted to be revolved, a-nd having a series of cavities provided with nipples g, in combination with sections G, provided with grooved ribs e', ttin g into the cavities in cylinder F, and having chambers d comvmunicating with the grooves in the ribs, the

and adapted to chambered and grooved sections G, in combi-Y nation with magazine H', having perforated bottoms h h2 h3 and intermediate perforated slides, h4 and h5, the slide h4 beingadapted to receive a ball, and slide h5 a charge of powder, the several parts being arranged and adapted to operate as set forth.

3. The revolving cylinder F, provided with chambered and grooved sections G, in combination with magazine H', having perforated bottoms and slides for the passage of balls and powder to the cylinder, the face of the magazine next to the cylinder being cut away so as to form a wedge-shaped cavity, as and for the purpose set forth.

4. The combination of cylinder F, provided with ratchet K' and chambered and grooved sections G, having cavities a', the collar K3, having a dog to engage with the ratchet, a
